Application filed September 29, 1910. Serial No. 584,491.

To all whom it may concern Be it known that I, ALrnnn Cantu, a subject of the Czar of Russia, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Machines for Applying Fly- Leaves or the like to Signatures of Books, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

llfiy invention relates in general to machines for binding books. i

In bind" 1g a book the most general method is to paste the fly leaf to the first page of the first signature and to the inside of the cover. In a book bound in this way, however, the fly leaf is very apt to be torn loose from the sheet of the signature to which it is pasted, and when it is so torn the cover will become detached from the body of the book. To obviate this disadvantage, a sys tem has been devised in which the inner edge of the fly leaf. is folded over the binding edge of the signature and pasted to the signature on the side opposite that on which the fly leaf is disposed. The signature and fly leaf may then be sewed together at the binding edge so that the binding is infinitely more secure than under the older system. This improved system, however, has heretofore been capable of use only by a hand operation, and consequently it has been both slow and expensive.

The present invention provides a machine capable of performing the operations necessary inthe employment of the improved system just described. The machine is not limited, however, to this one use, but is ca pablo of performing other similar opera tions which will be noted hereafter.

To the accomplishment of these and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings :F;igure 1 is a plan view of a machine embodying my invention, the arrows in Figs. 1, 2,3 and (3 indicating the direction of movement of the work. Fig. 2 is a side elevation thereof; Fig. 3 is a broken vertical section on the line A A. in Fig. 1; Fig. 4: is a broken vertical section on the line B-B in Fig. 1; Fig. 5 is a broken vertical section on the line C- C in Fig. 1; Fig. 6 is a broken side ele vation of a modified formof the machine;

Fig. 7 is a broken vertical section on the line D,D in Fig. 6; and Fig. 8 is anend view of the product on a larger scale than the other figures.

The machine comprises two standards 1 "to the front of which is secured a shelf 2 provided with suitable gauges 30 for centering the signature and fly leaf. J ournaled in the two standards 1 are a plurality of pairs of alined shafts carrying paired rolls 3, the shafts being rotatable and adapted to be driven by any suitable driving mechanism. One of the shafts in each pair is supported in a verticallyadjustable journal box 18 so that the space between the two rolls 3 of each pair may be varied as desired by means of screws 19. Two axially spaced rotatable disks 4: are secured to a shaft whose axis is parallel with, and in the same plane with, the axes of either the upper or lower shafts of the series which carry the rolls 3;

another rotatable disk 5 is disposed below or,

above the disks 4, as the case may be, and opposite the space between the two axially spaced disks. Below the series of alined rolls is a paste receptacle 6 which is mounted on a rack member 7 meshing with a pinion 8 on a shaft 9, and into this receptacle 6 extends a rotatable disk 10 which is carried by a shaft whose axis is parallel with, and in the same plane with, the axes of the shafts carrying the lower rolls 3, a roll 11 being:

disposed opposite the disk 10. Another disk 12 is rotatable in a plane parallel to the plane in whichthe disk 10 lies and their axes are parallel, so that disks 10 and 12 are spaced from each other and the lines of their circumferences out each other. A convenient manner of mounting theseveral disks described is to carry them on the respective shafts to which are secured the conveying rolls 3, but they may be carried by separate shafts, if desired. In advance of disks 10 and 12,.two horizontal plates 13 and 14 are disposed parallel to each other so that 3 adhesive substance.

they form a horizontal slot in the plane in which the rolls 3 of the alined pairs contact, and the rear part of the bottom wall of this slot is bent downwardly away from the normal plane of the wall, as at 15. Disposed at the rear of the machine is a plate 16 alined with the pairs of rolls 3 and inclined downwardly therefrom toward the front of the machine, while a second series of alined pairs of rolls 17 inclines downwardly from the plate 16 and extends below the rolls 3 of the first series.

When the machine is in operation the receptacle will be supplied with glue or other The signature will be placed upon the shelf at the front of the machine with its folded edge alined with rolls 4, and the fly-leaf will be placed on top of the signature with its one edge extending beyond the edge of the signature. The signature and fly-leaf together will then be pushed between the rolls of the first pair, which will draw the two sheets of material forwardly together. As they pass the spaced disks, the disk opposite the space between them pushes the fly leaf F, along the edge of the signature S, slightly into the space between the axially spaced disks, and thus forms a crease in the fly leaf along the edge of the signature. The succeeding rolls convey the sheets of material to the paste receptacle and to the rotatable disk which extends into the receptacle, and as it progresses in contact with this disk, the disk cooperating therewith engages the edge of the fly leaf F along the crease therein and bends the marginal portion of the leaf downwardly along the crease at a right angle to the body of the sheet. At the same time the disk which extends into the receptacle and which, of course, is covered both laterally and periph erally with the adhesive substance, applies such substance to the inner side of the right angled or marginal portion of the fly leaf and to the under side of the signature. The two sheets in their further progress strike the horizontal slot, and the bottom wall thereof, which is bent downwardly, engages the portion of the fly leaf which is turned at a right angle to the body of the sheet, and as the sheets move into the slot this right angled portion is folded back under the signature and parallel to the body of the leaf and folio. The succeeding rolls convey the sheets along and press them together so that when they emerge from the rolls the fly leaf is folded over one edge of the signature, and the two are securely glued together. They may then be sewed.

The rolls of the second series declining downwardly below the first series of rolls are for the purpose of applying further pressure to the two sheets; obviously the plate will transfer the sheets from the first to the second series of rolls, and the latter are so rotated as to deliver the united sheets to the front of the machine, where a re ceptacle will be provided.

Instead of mounting the receptacle for the glue below the rolls, I may mount it on a cross bar 20 extending parallel to the shafts which carry the rolls 3 and above them, see Fig. 6. In such case a rod 28 will be suspended from bar 20 and will be horizontally movable thereon, and a rod 27 carrying the receptacle will be secured to rod 28 by thumb-screw 29, so as to be capable of vertical adjustment. The receptacle 26 in such case will be formed with outwardly convex top and bottom 21 uniting at opposite ends of the receptacle in flat horizontal plates 22 which extend between the two'rolls 3 of the adjacent pairs, a disk 28 running in the receptacle and a roller 25 contacting therewith. The roller 25 is peripherally grooved so that it will direct the advancing sheet downwardly. A. device 24 is carried by the receptacle for supplying glue thereto. Such a receptacle will preferably be used when no folding operation is desired, but when two sheets are to be pasted togather along one edge. A receptacle of this shape may also be advantageously utilized in connection with my machine if an insert is to be pasted along the center of a sheet, for the receptacle may be moved to the center of the machine on its cross bar, and as the sheet and insert meet the receptacle,the sheet will pass belo-w, and the insert above, the receptacle, and the insert above will come into contact with the disk which extends into the glue in the receptacle. The succeeding rolls will then press the insert firmly to the sheet.

Certain books are made with flexible covers which are formed by folding the covering over the edges of a flexible sheet and gluing it to. the sheet. My machinemay be readily made to perform this operation by mounting duplicate gluing and folding devices at the two sides of the machine. The sheet and covering are put through the machine, which folds and glues the covering along two opposite edges of the sheet. The sheet is then turned'to a position at a right angle to its first position and put through the machine a second time, so that the remaining two opposite edges of the covering are folded and glued tothe sheet, whereupon the cover is complete.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
